"Secretaries, look!" begins a typewriter ad from around 1955. "Look how Underwood and Underwood alone helps your keep fingernails and hands lovely to look at, lovely to touch!"

And that's not all: "Try Underwood's new chip-resistant nail polish, Underwood's Red, free! Beauty consultants styled it just for secretaries. A brilliant red, it stays on and on. Type us a letter on office stationery asking for it." How badly do you wish this were still available so that you could test-drive it? (Click picture to see a larger version.) [Vintage Ads]
